1 FUNCTIONS
1.1 EtherNet/IP Communication Functions
Server function
With the UCMM message communication server function, when the RJ71EIP91 receives a command request from an
EtherNet/IP device, the RJ71EIP91 executes the command processing and returns the command response.
UCMM message communications with the server function is performed according to the following procedure.
1.
Starting the EtherNet/IP communication start request ((1) shown above)
Turn on 'EtherNet/IP communication start request' (Y10) on the RJ71EIP91 on the server side.
2.
Command request acceptance and response ((2) to (4) shown above)
When the RJ71EIP91 receives the command request from the EtherNet/IP device with arbitrary timing, the RJ71EIP91
executes the command processing and returns the command response to the EtherNet/IP device.
For the operation timing of EtherNet/IP communications, refer to the following.
